Most fish don't die suddenly.
They suffer slowly while
their owner doesn't notice.

01

Your water test app doesn't know when you last did a water change

Every aquarium app logs your parameters. None of them connect those parameters to your maintenance history. So when your nitrate is high β€” they show you the number but can't tell you why.

02

Generic AI gives generic answers regardless of your tank

Ask any AI assistant why your nitrate is high and you get the same answer every time β€” regardless of your tank size, your stocking, your filter or how long it's been since your last water change.

03

Nobody warns you before the ammonia spike kills your fish

Ammonia spikes don't happen overnight. The warning signs build over weeks. Without something watching your complete history β€” you only notice when it's too late.

πŸ‘€
Why is my nitrate high?
🐠
Your Mbuna Tank (180L) β€” nitrate is at 50ppm because waste is building up faster than it's being removed.

Your last water change was 16 days ago (25%) and filter clean was 45 days ago β€” both overdue for a heavily stocked cichlid tank.

πŸ’§ To bring nitrate from 50ppm down to 10ppm in your 180L tank β†’ 80% water change = 144 litres

What to Look For in an Aquarium AI App

Not all aquarium apps are equal. Here's what separates a genuinely useful tool from a generic one.

01

Does it actually know YOUR tank?

Generic AI gives generic answers. A proper aquarium assistant remembers your specific fish, your filter, your water history and your maintenance β€” and uses all of it in every response.

02

Does it tell you WHY β€” not just WHAT?

Showing you a high nitrate reading is easy. Explaining that it's high because your last water change was 16 days ago and calculating exactly how many litres to change β€” that's intelligence.

03

Can it read your test results from a photo?

Manually entering water parameters is error-prone and tedious. AquaBuddyAI uses AI vision to read your test kit photo directly β€” saving time and removing human error.

04

Is it built by someone who keeps fish?

There's a significant difference between an app built by a tech company and one built by a hobbyist who actually keeps Mbuna cichlids and loses sleep over water parameters.

"I built the tool I always wished existed β€” because nobody else was going to do it the right way."
Zero coding experience β†’ Category-leading iOS app in 6 months

Built by a Hobbyist.
For Hobbyists.

If you had told me a year ago that I would build a category-leading, multi-agent AI fishkeeping app, I would have laughed. Before I started this journey, I hadn't touched or operated a computer since 1998.

Then, life threw a massive curveball. I faced a serious health scare that forced me to slow down physically, but my mind needed a challenge. I decided to dive headfirst into the deep end of modern software engineering. I taught myself the terminal, mastered database architecture, and learned how to orchestrate cutting-edge artificial intelligence.

Six months of intense, obsessive coding later, AquaBuddyAI was born.

Why I Built It: I didn't want to build another lazy AI chatbot or a generic prompt wrapper. Hobbyists don't need a robot that just googles things for them β€” they need real, undeniable utility. In fishkeeping, credibility is life or death for our livestock. If an app misreads an ammonia spike due to room glare, a tank crashes.

So I built AquaBuddyAI to be better than the human eye. Instead of guessing liquid kit gradients, AquaBuddyAI uses CIEDE2000 colour science to calculate the exact mathematical distance of colour shifts, turning your iPhone camera into a digital colorimeter.

When you ask for help, the app doesn't fire a single text prompt. It orchestrates four separate multimodal AI agents per API call β€” a vision specialist, a historical memory engine, a pathology critic, and a synthesis orchestrator β€” to deliver clinical-grade pathology reports.

I am playing the long game. I want AquaBuddyAI to be a daily tool you can rely on forever, which is why water parameter testing is free for life. You only tap into the heavy cloud API when you face an emergency and need a full pathology report to save your tank.

Now we are tackling the final frontier with the AquaBuddyAI LabDockβ„’ β€” a custom-manufactured precision water testing dock with calibrated LED lighting that locks in 98%+ testing accuracy.

Tips & Advice

Expert fishkeeping advice from a real hobbyist. No corporate fluff β€” just the stuff that actually helps.

Frequently Asked Questions

Does AquaBuddyAI read API and NT Labs water test kits?

Yes. AquaBuddyAI's Smart Water Lab uses CIEDE2000 colour science to read API Freshwater Master Test Kit and NT Labs liquid test kits from a photograph. Accuracy up to 98% on supported kits.

What is an Aquarium Tank Score?

The Tank Score is a dynamic health grade for your ecosystem. The AI evaluates your bioload, hardware runtimes and parameter history into a single score telling you how to fix issues before they threaten your livestock.

How does the AI remember my specific aquarium setup?

AquaBuddyAI uses persistent RAG memory. Unlike basic chatbots, the AI saves your livestock profiles, filtration gear and tank type using your historical data to provide precise customised advice every time.

Can I manage multiple aquariums at the same time?

Absolutely. The multi-tank dashboard lets you view parameters for a tropical freshwater tank, Mbuna cichlid setup or marine reef simultaneously without cross-contaminating your AI tracking history.

What is the AquaBuddyAI LabDock?

The LabDock is a precision water testing dock with calibrated LED lighting that eliminates ambient light variables β€” the biggest cause of inaccurate colour test readings. Combined with locked camera technology, it achieves 98%+ accuracy.

Is Android supported?

AquaBuddyAI is currently iOS only. Android is actively in development and coming very soon. Register your interest to be notified when it launches.
